Technical Field
[0001] This utility model relates to the field of paper feeding device technology, and in particular to a rapid adjustment device for the paper feeder roller. Background Technology
[0002] Paper feeders are core equipment in printing, packaging, and papermaking production lines, primarily used for the automated, precise, and continuous feeding of paper or roll materials. The paper feed rollers are the core transmission components of the paper feeder, mainly responsible for precisely controlling the paper's feeding speed, direction, and position to ensure the paper smoothly and continuously enters the processing station (such as printing and die-cutting).
[0003] Currently, the height of the paper feeder rollers is usually fixed, which is not conducive to adjusting the height of the rollers according to the paper thickness. This means that the rollers can only transport paper of a single thickness, and it is also not conducive to adjusting the position of the rollers on the paper. This greatly reduces the applicability of the rollers and the practicality of the device. Therefore, it is necessary to design a quick adjustment device for the paper feeder rollers that can easily adjust the position and height of the rollers. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology where the height of the paper feeder roller is usually fixed, which is not conducive to adjusting the height of the paper feeder roller according to the thickness of the paper, meaning that the paper feeder roller can only transport paper of a single thickness, and also not conducive to adjusting the position of the paper feeder roller on the paper, one of the purposes of this utility model is to provide a quick adjustment device for the paper feeder roller.
[0005] One of the objectives of this utility model is achieved by the following technical solution: a paper feeder roller quick adjustment device, including a frame: a support plate is provided on one side of the frame, an adjustment mechanism is provided on the upper surface of the frame near the support plate, and a paper feeding mechanism is provided on the side of the frame near the adjustment mechanism.
[0006] The adjustment mechanism includes a fixed plate 1 fixed to the inner wall of the frame, uprights symmetrically fixed to the fixed plate 1, a support plate 2 fixed to the uprights, a rack fixed to the support plate 2, a sliding frame slidably connected to the support plate 2, a rotating wheel rotatably connected to one side of the sliding frame, a rotating rod fixed to one side of the rotating wheel, rotating gears symmetrically mounted on the rotating rod, a support frame equidistantly mounted on the sliding frame, and a paper feeding wheel assembly and a brush assembly mounted on the support frame. The paper feeding wheel assembly includes a fixed block fixed to one side of the support frame, a fixed plate 2 fixed to one side of the fixed block, a snap-fit plate slidably connected to the lower part of the fixed plate 2, a support shaft fixed to one side of the fixed block, a rotating plate rotatably connected to the support shaft, a snap-fit groove on the rotating plate, a roller rotatably connected to one side of the rotating plate, a limiting hole 1 and a limiting hole 2 on the fixed plate 2 and the snap-fit plate, and a limiting rod threadedly connected to the inner wall of the limiting hole 1. The rotating gear is meshed with the rack. It is easy to adjust the position and height of the paper feed rollers on the paper, making it convenient to use.
[0007] According to the aforementioned paper feeder roller quick adjustment device, the number of the locking slots is two, and the two locking slots are formed on the rotating plate. The locking slots are engaged with the locking plate in a limiting engagement manner, thereby achieving a stable limiting engagement and limiting the height of the paper feed roller.
[0008] According to the aforementioned paper feeder roller quick adjustment device, the structure and working principle of the brush assembly are consistent with those of the paper feed roller assembly. The difference between the brush assembly and the paper feed roller assembly lies in that the rollers of the brush assembly are arranged in a circular array of brushes, facilitating paper separation.
[0009] According to the aforementioned paper feeder roller quick adjustment device, a support block is bolted to one side of the sliding frame, and the rotating rod movably passes through the support block. An abutment rod is threaded onto the upper surface of the support block, and an annular abutment surface is provided on the side of the rotating rod near the abutment rod. This facilitates the positioning of the roller.
[0010] According to the aforementioned paper feeder roller quick adjustment device, the outer diameter of the limiting rod is adapted to the inner diameter of both the first limiting hole and the second limiting hole. This facilitates the limiting of the locking plate and improves the locking stability of the locking plate.
[0011] According to the aforementioned paper feeder roller quick adjustment device, the paper feeding mechanism includes a paper feeding platform fixed to one side of the fixed plate, grooves equidistantly formed on the upper surface of the paper feeding platform, a variable frequency speed control motor fixed to the inner wall of the frame, a drive gear installed at the output end of the variable frequency speed control motor, driven gear one and driven gear two meshing with the outer wall of the drive gear, driven gear three meshing with one side of driven gear two, a rotating shaft rotatably connected to one side of driven gear one and driven gear three, and paper feeding rollers equidistantly installed on the outer wall of the rotating shaft. The paper feeding rollers facilitate paper feeding.
[0012] According to the aforementioned paper feeder roller quick adjustment device, the size of the trough is larger than the size of the paper feed roller, and the paper feed roller is rotatably connected to the inner wall of the trough. This ensures the rotational stability of the paper feed roller.
[0013] According to the aforementioned paper feeder roller quick adjustment device, a controller and a control panel are installed on the side wall of the frame, and the control panel and the controller are electrically connected to achieve automatic control.
[0014] The above-mentioned solution has the following beneficial effects:
[0015] Compared with existing technologies, this device can adjust the height of the rollers and brushes within a certain range through the adjustment mechanism, making it easier to separate and transport paper. It is convenient to use and effectively improves the convenience and practicality of the device. Furthermore, by setting the abutment rod and the annular abutment surface, the rotation of the roller can be restricted, thereby preventing the roller from rotating and driving the rotating gear, and thus preventing the paper feeding roller assembly from shifting position. It is also convenient to use.

[0030] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0031] Reference Figures 1-10 A rapid adjustment device for the paper feed rollers of a paper feeder includes a frame 1. A support plate 2 is provided on one side of the frame 1. An adjustment mechanism 3 is provided on the upper surface of the side of the frame 1 near the support plate 2. A paper feeding mechanism 4 is provided on the side of the frame 1 near the adjustment mechanism 3. The adjustment mechanism 3 includes a fixing plate 300 fixed to the inner wall of the frame 1, uprights 301 symmetrically fixed to the fixing plate 300, a support plate 302 fixed to the uprights 301, a rack 303 fixed to the support plate 302, a sliding frame 304 slidably connected to the support plate 302, a rotating wheel 305 rotatably connected to one side of the sliding frame 304, a rotating rod 306 fixed to one side of the rotating wheel 305, and rotating rods symmetrically mounted on the rotating rod 306. The components include a gear 307, a support frame 308 equidistantly mounted on the sliding frame 304, and a paper feeding roller assembly 309 and a brush assembly 310 mounted on the support frame 308. The paper feeding roller assembly 309 includes a fixing block 3090 fixed to one side of the support frame 308, a second fixing plate 3091 fixed to one side of the fixing block 3090, a snap-fit plate 3092 slidably connected to the lower part of the second fixing plate 3091, a support shaft 3093 fixed to one side of the fixing block 3090, a rotating plate 3094 rotatably connected to the support shaft 3093, a snap-fit groove 3095 formed on the rotating plate 3094, a roller 3096 rotatably connected to one side of the rotating plate 3094, and a roller formed on the second fixing plate 3091 and the snap-fit plate 3092. The system includes a first limiting hole 3097, a second limiting hole 3098, and a limiting rod 3099 threadedly connected to the inner wall of the first limiting hole 3097. A rotating gear 307 meshes with a rack 303. Two locking slots 3095 are provided on a rotating plate 3094, and these slots engage with a locking plate 3092. The structure and working principle of the brush assembly 310 are consistent with those of the paper feed roller assembly 309. The brush assembly 310 differs from the paper feed roller assembly 309 in that brushes 5 are arranged in a circular array on the roller 3096 of the brush assembly 310. A support block 6 is bolted to one side of the sliding frame 304. The rotating rod 306 is movable. A connecting rod 7 is threaded onto the upper surface of the support block 6. An annular contact surface 8 is provided on the side of the rotating rod 306 near the connecting rod 7. The outer diameter of the limiting rod 3099 is adapted to the inner diameter of the first limiting hole 3097 and the second limiting hole 3098. The height of the roller 3096 and the brush 5 can be adjusted within a certain range by the adjusting mechanism 3, so that it can easily separate and transport paper. It is convenient to use and effectively improves the convenience and practicality of the device. Furthermore, by setting the connecting rod 7 and the annular contact surface 8, the rotation of the rotating wheel 305 can be restricted, thereby preventing the rotating wheel 305 from driving the rotating gear 307 to rotate, and thus preventing the position of the paper feeding roller assembly 309 from being offset. It is convenient to use.
[0032] The paper feeding mechanism 4 includes a paper feeding platform 40 fixed to one side of the fixed plate 300, slots 41 equidistantly formed on the upper surface of the paper feeding platform 40, a variable frequency speed control motor 42 fixed to the inner wall of the frame 1, a drive gear 43 installed at the output end of the variable frequency speed control motor 42, driven gear 44 and driven gear 45 meshing with the outer wall of the drive gear 43, driven gear 46 meshing with one side of driven gear 45, a rotating shaft 47 rotatably connected to one side of driven gear 44 and driven gear 46, and equidistantly mounted... The paper feeding roller 48 is located on the outer wall of the rotating shaft 47. The size of the trough 41 is larger than the size of the paper feeding roller 48. The paper feeding roller 48 is rotatably connected to the inner wall of the trough 41. The side wall of the frame 1 is equipped with a controller 9 and a control panel 10. The control panel 10 and the controller 9 are electrically connected. The paper feeding mechanism 4 facilitates the feeding of paper. With the cooperation of the controller 9 and the control panel 10, it is easy to control the start and stop of the variable frequency speed control motor 42. It is convenient to use. Both the controller 9 and the control panel 10 are powered by an external power source.
[0033] Working principle: Place the paper on support plate 2, adjust the position of paper feed roller assembly 309 and brush assembly 310, first adjust their position on frame 1, rotate the abutment rod 7 to move it upward on support block 6 and out of the abutment limit annular abutment surface 8, unlock the rotating wheel 305, rotate the rotating wheel 305 to drive the rotating rod 306 to rotate, the rotating rod 306 drives the two rotating gears 307 to rotate, the rotating gears 307 mesh with the rack 303. Since the rack 303 is fixed, the rotating gears 307 move on the rack 303, the rotating rod 306 rotates and connects On the sliding frame 304, the sliding frame 304 is driven to move on the support plate 302. After the paper feeding roller assembly 309 and the brush assembly 310 are adjusted to the appropriate position, the rotating wheel 305 is stopped and locked. The abutment rod 7 is rotated so that it moves downward on the support block 6 and abuts against the annular abutment surface 8, thereby limiting the rotating rod 306. When the rotating wheel 305 rotates, the abutment rod 7 applies pressure to the rotating rod 306, thereby limiting the rotation of the rotating rod 306, thus preventing the rotating gear 307 from rotating on its own and changing the position of the paper feeding roller assembly 309 and the brush assembly 310.
[0034] Then adjust the height of the paper feed roller assembly 309 and the brush assembly 310. Rotate the limiting rod 3099 to make it rotate upward within the limiting hole 3097 of the locking plate 3092 and the fixing plate 3091, and no longer limit the locking plate 3092. Move the locking plate 3092 to disengage it from one of the locking slots 3095 on the rotating plate 3094. Rotate the rotating plate 3094 to make the roller 3096 rotate downward, aligning the other locking slot 3095 with the locking plate 3092. Push the locking plate 3092 back and insert it into the locking slot 3095. Screw the limiting rod 3099 into the inner wall of the corresponding limiting hole 3097 or limiting hole 3098 to ensure locking stability. The adjustment method of the brush assembly 310 is the same as that of the paper feed roller assembly 309, so it will not be described in detail. This can meet the usage requirements within a certain range.
[0035] Paper is fed by the paper feeding mechanism 4. The variable frequency speed control motor 42 is started by the control panel 10 and the controller 9. The variable frequency speed control motor 42 drives the drive gear 43 to rotate. The drive gear 43 rotates and meshes with the driven gear 1 44 and driven gear 2 45, driving the driven gear 1 44 and driven gear 2 45 to rotate. The driven gear 2 45 rotates and meshes with the driven gear 3 46, driving the driven gear 3 46 to rotate. The rotation of driven gear 1 44 and driven gear 3 46 drives the rotating shaft 47 and the paper feeding roller 48 to rotate. The paper feeding roller 48 drives the paper to be fed by friction with the paper. During the paper feeding process, the roller 3096 assists in the paper feeding. The brush 5 can separate the paper to prevent two sheets of paper from being fed at the same time. The practicality and convenience of the device can be improved by adjusting the mechanism 3 and the paper feeding mechanism 4.
[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
